python - 文件未找到错误: [Errno 2] No such file or directory: '/opt/caffe/build/tools/caffe' : '/opt/caffe/build/tools/caffe'

Question

我通过 apt install 命令在我的 Ubuntu v18 VM 上安装了 caffe-cpu。我正在努力找出安装目录所在的位置，如果我错了请纠正我，但我相信没有安装目录。我尝试执行的 NN 模型需要 caffe 中的构建工具路径。我怎样才能获得这个？我在任何地方都没有看到任何有关此的信息。

caffe 的 Ubuntu 软件包将 caffe 可执行文件安装在 /usr/bin 中。您想要的特定文件位于 caffe-tools-cpu 中，而不是 caffe-cpu 中。
